The slider sets the power saving mode of the wifi radio. It allows the radio to go to sleep and power down parts of its circuits. The radio will then periodically wake up to check to see if it has any data waiting for it at the access point.

The power savings can be significant, but it slows down throughput.

Conversely, on best performance the radio is always fully powered and ready to receive. The access point can send data immediately and not wait for the radio to wake up and poll it. (Check out 802.11 power save mode on google if you want to know more about it.)
